Number11, does the "left" location of the coolant leak mean when you're looking from the front of the engine or from the driver's seat? If it's on the driver's side it may very well be from the water pump weep hole ... which means the pump is shot and needs replaced. Have a tech confirm that the water pump is shot before going that route as the replacement labor will be quite costly, not to mention the cost of a new water pump. If a hose connection is leaking try tightening the associated hose clamp and see if that stops the leak.
